## Descriptor that Calculates the LogP Based on a Simple Equation Using the Number of Carbons and Hetero Atoms

### Description

Descriptor that Calculates the LogP Based on a Simple Equation Using the Number of Carbons and Hetero Atoms

### Usage

    extractDrugMannholdLogP(molecules, silent = TRUE)

### Arguments

`molecules` | Parsed molucule object.
`silent` | Logical. Whether the calculating process should be shown or not, default is `TRUE`.

### Details

This descriptor calculates the LogP based on a simple equation using the number of carbons and hetero atoms. The implemented equation was proposed in Mannhold et al.

### Value

A data frame, each row represents one of the molecules, each column represents one feature. This function returns one column named `MLogP`.
